Spyware is any technology that aids in gathering information about a person or organization without their knowledge. Adware is any software application in which advertising banners are displayed while the program is running.

How did I get this on my computer?

Spyware applications are typically bundled as a hidden component of freeware or shareware programs that can be downloaded from the Internet. However, some spyware can be installed without the user’s consent, as a “drive-by download,” or as the result of clicking some option in a deceptive pop-up window.

What could/does spyware do?

Common examples include:

Monitor and record your keystrokes

Collect information about you and your surfing habits

Modify your system settings

Redirect your browser

Leave a backdoor open for hackers & viruses

Install other programs directly onto your PC

Load adult-orientated images on your PC

Dial a service (if you still have a modem), for which you will be billed!

What does this mean to me, Shawn?

Spyware is an unfortunate part of Internet life now, and the best offense is a good defense. Here are some things you can do to prevent spyware:

Keep Windows and your antivirus software up to date

Install software only from Web sites you trust

Read the fine print on free software. “There is no such thing as a free lunch.”

Use a tool to help detect and remove unwanted software. Some good free ones include Spybot and Ad-Aware. Get both to cover as many threats as possible.

Spyware and viruses are related and tend to travel together. If you have one on your computer, you will surely have the other soon.

What you said about “Read the fine print on free software”.
You really have to be careful.
Before you click the “I Agree” button, read the agreement.
Although some make the agreement impossibly long just to get you to agree.
Great Post!
